hello
to solve this question, we just need to imput the value of x and solve the equation to get y
a. when x = 15
the equation is
[tex]\begin{gathered} y=-2.1x+0.43 \\ x=15 \\ y=-2.1(15)+0.43 \\ y=-31.07 \end{gathered}[/tex]when x = 0
[tex]\begin{gathered} y=-2.1x+0.43 \\ x=0 \\ y=-2.1(0)+0.43 \\ y=0.43 \end{gathered}[/tex]when x = 4.5
[tex]\begin{gathered} y=-2.1x+0.43 \\ x=4.5 \\ y=-2.1(4.5)+0.43 \\ y=-9.02 \end{gathered}[/tex]when x = 7.1
[tex]\begin{gathered} y=-2.1x+0.43 \\ x=7.1 \\ y=-2.1(7.1)+0.43 \\ y=-14.48 \end{gathered}[/tex]
